To all whom t may concern.'

Be it known that l, FRITZ NEPPACH, a subject of the German Emperor, and resident of Stuttgart-Cannstatt, Germany, have invented certain new and useful limprovements in Clamps, of which the following is a specification.

My invention relates to a novel clamp for keeping an object having a plurality of parts in compressed or assembled condition, or for fastening a hollow body of `yielding material, for instance a hose, upon a rigid body, for instance a metal pipe, and more particularly in such a manner that a closle fit will be secured between said 'two bodies.

The device of my invention is especially designed to meet the demand for aproper device of this latter class, which is independent from the diameter of the parts to be joined and which mayl therefore be conveniently used for hose-connections of the various diameters found'in practice.

The clamp vof my present invention is especially well suited for the purpose of mak- 4 ing hose and pipe connections in all kinds of engines, apparatus for compressed air or steam, automobiles and so forth, wherein a great number of dierentdiameters are existing.

Regarding the irstmentioned purpose it may be remarked that I regard the device of e my invention particularly advantageousfor work with pieces compod of a plurality of parts" which must be kept properly assembled during the working process. For applying the clamp it is immaterial 'whether the cross-section of such working piece is round, oval or of other form, orywhether the cross-section is of different form on different places.

For the purpose of convenient adjustment the device of my present invention vcomprises as an essential element atribbon, band or tape, preferably of metal, which can easily be made of greater or-smaller length to lit any existing size or diameter of the members to be `jolned.

My invention will be more fully understood by reference to the accompanying drawings, of which-9 l' Figure 1 is a front view showing a hinge with eyes for the reception of a bolt and a tape which is fastened to said hinge by becation of the clamp for fastening a hinge b which is provided at the outer ends of its shanks with openings or eyes e and d serving for the reception of the screw bolt f having a slot e, and the nut g which may .l be threaded upon said bolt for locking the same in position. The tape or strap a is doubled over the cross bar of member b, and is held thereto by frictional contact, so that any eyes, slits or other mutilations of the strap are entirely obviatedywhile'the strap may furthermore be secured to said member at each point of its length.

The bolt f is rotatably mounted in the eyes c and d, and may be locked in position by the nut y which when drawn tight will iirmly unite the bolt with the hin e b and therewith also keep the tape a whifc is laid around the hose to be fastened in stretched condition. The clamp is applied to the hose and pipe as shown in Figs. 5 and 6 in such a manner that the ribbon a is wound ina single turn or in several turns one above the other around the hose, passed througbfthe space-between the hinge b and the bolt f and then inserted into the slot e which is ro- -vided in said bolt. By rotation of the olt the ribbon a will be wound up around the same and thus be drawn tivht around the hose z-,thereby pressing theatter upon the end of the pipe z", whereupon the nut g is drawn tight and the bolt locked in' position.

- having eyed Shanks; a strap doubled at one v of its ends over the cross bar of said memset my signature in the presence of two subber, a screw bolt engaging the eyed Shanks, scribing Witnesses. and having a longitudinal slot adapted to FRITZ NEPPACH. be engaged by the othel:` end of sid strap, Vitnesses: v 4 5 and a locking nut fitted upon the bolt.
